I am delighted to share that @clavedec.bsky.social's latest paper on the association between DNA methylation and cuticular hydrocarbons in Timema stick insects has now been published in Phil Trans of the Royal Society B #speciation #epigenetics #matechoice royalsocietypublishing.org/rstb/article...

Genomic regions exhibiting divergent DNA methylation patterns co-vary with loci associated with sexual signalling traits in a stick insect
Abstract. The evolution of signalling traits can affect local adaptation, mate choice and the development of reproductive isolation between diverging popul

Excited to share our new paper, led by Brazilian collaborators, on male coloration of guppies in response to urban pollution: www.sciencedirect.com/science/arti... @rhulbiology.bsky.social
This is a graphical abstract, showing that male nuptial color changes with increasing pollution. Guppies in more polluted waters develop more intense white ornaments and increase the number and body area covered by violet color ornaments.

I recently wrote about a cool new paper by another research group on Antarctic leopard seal communication for The Conversation; it was fun to focus on some #bioacoustics again for a change. 😃 theconversation.com/antarctic-le...

Antarctic leopard seal ‘songs’ are surprisingly similar to nursery rhymes
The fact that animals don’t use words makes it hard to decode their communication. But technology is starting to make it easier.

Happy 99th birthday to the man who gave voice to the wild. 🎉 Sir David Attenborough, thank you for a lifetime dedicated to the natural world, and for sharing its story with wisdom, wonder, and grace. You've inspired generations to fall in love with nature.
This photograph captures Sir David Attenborough seated outdoors on the rugged terrain of Skomer Island. Behind him, the ocean and coastal cliffs form a scenic backdrop under a clear sky. Sir David, dressed in a khaki jacket and light trousers, looks towards the camera with a gentle expression, exuding a sense of warmth, calm, and wisdom. Around him, puffins can be seen flying and perched on the rocky ground, illuminated in rays of golden sunlight as the sun sets behind the cliffs.
